Cartridge case ejector in a firearm to be opened by breaking

ABSTRACT

For a firearm which is opened by breaking it and in which a cartridge with grooved base is used, an ejector is disclosed which moves backwardly when the firearm is opened. The invention is particularly characterized in that the ejector, which moves in a guiding groove in the firearm, and said groove are so shaped that when the ejector moves backward on opening the firearm, the ejector bends to the side, whereby a prong on the ejector moves in outwardly direction from the groove in the base of the cartridge case.

INVENTOR: LIZ/Woman (MUM-MM fiw ATTorLNEs5 CARTRIDGE CASE EJECTOR IN A FIREARM TO BE OPENED BY BREAKING The present invention concerns an elastic ejector in a firearm which is opened by breaking it and in which a cartridge with grooved base is used, which ejector moves backwardly when the firearm is opened. The firearm may be of any kind whatsoever, as long as it is designed to be opened by breaking. For instance, the invention is suitable for use in a shotgun-and-rifle combination firearm. In such firearms in which a cartridge with grooved base is used, the stem of the ejector must be elastic for the purpose of inserting a cartridge in the barrel and for removing it. In firearms to be opened by breaking the ejection travel of the cartridge case is comparatively short and the taper of the cartridge case is small, for which reason removal of the cartridge case by hand is difficult when the prong of the ejector fouls the groove in the base of the cartridge case.

The aim of the invention is to remove the abovementioned drawback. The invention is mainly characterized in that the ejector comprised in the firearm, which moves in a guiding groove, and the said guiding groove are so shaped that when at opening of the firearm the ejector is backwardly displaced it bends to the side, whereby the prong on the ejector moves from the groove at the base outwardly. The ejector may bend to the side in such amount only that the prong on it only comes partly out of the groove at the base, which is ad vantageous when the cartridge case has to be removed by hand. In case the cartridge case ejector is operated by an ejector mechanism, then it is most appropriate to make the sidewise bending of the ejector such in magnitude that the prong of the ejector comes completely out of the groove of the cartridge case, permitting the cartridge case freely to fly out of the barrel. The sidewise bending of the ejector's stem can be most suitably achieved in that on the stem of the ejector there is an eminence, and in the guiding groove a rising plane, along which the said eminence moves when the ejector moves backwardly, with the consequence that the ejector is bent to the side.

The invention is described in greater detail with reference to the embodiment example presented in the attached drawing.

In the drawing,

FIG. 1 represents the set of barrels of a firearm provided with a shotgun barrel and a rifle barrel, as seen from the loading end.

FIG. 2 shows the same set of barrels in section along line A-A, when the firearm is loaded.

FIG. 3 also shows the same set of barrels, in section equivalent to that of FIG. 2, but with the firearm broken open.

FIG. 4 likewise shows the same set of barrels, but sectioned along the line B-B in FIG. 2.

The firearm shown in the drawing has a shotgun barrel 1 and a rifle barrel 2. In the guiding groove 3 in the body part between the said barrels there is an elastic ejector 4 for the cartridge cases. This ejector has in a manner previously known in itself been arranged to be moveable when the weapon is broken open. On the stern of the ejector there is an eminence-5, and the guiding groove in which the ejector moves has been so shaped that when the ejector is backwardly displaced on opening the weapon by breaking, the eminence 5 of the ejector moves along the risin surface 6 of the groove 3. From this follows that the e ector IS bent to the side. The prong plate 7 at the end of the ejector then also moves to the side, whereby the prongs 8 and 9 of the said prong plate 7 move in the direction away from the cartridge cases l0, 11, yet so that the prongs still remain under the bases of the cartridge cases (FIG. 3). As a result, the rifle cartridge case 11 provided with a groove 12 is easy to remove.

It is previously known to connect the cartridge case ejector to an ejector mechanism. In that case it is most appropriate to make the sidewise bending of the ejector 4 to be of such magnitude that the prong comes completely out of the groove of the cartridge case, so that the cartridge case can freely fly out from the barrel.

The invention is by no means merely confined to the embodiment example presented above; it may be modified within the scope of the invention. For in stance, the firearm must not be a shotgun-rifle combination; the invention is rather suitable to be used on any firearms which are opened by breaking them and in which a cartridge with a groove at its base is used.

I claim:

1. In a firearm of break-down type an ejector for a cartridge case having a groove at its base, comprising an oblong, elastic arm, at the end of this arm a prong which engages the groove at the base of the cartridge case, a guiding groove in the body of the firearm, in guidance by which groove said arm moves axially when the firearm is broken performing ejection of the car tridge case, an ascending surface in the part of the bottom of said guiding groove adjacent to the base of the cartridge case, and a stop member on said arm opposite to said ascending surface in the range of the ejection travel so that at the rearward displacement of the arm when the firearm is broken, when said ascending surface and stop member meet the end of said arm is laterally deflected so that its prong moves outwardly from the groove of the cartridge case.

2. Ejector according to claim 1, wherein the ascent of said ascending surface has a magnitude such that said prong is completely removed from the groove of the cartridge case.

3. Ejector according to claim 1, wherein said stop member is a pin attached to said arm. 

1. In a firearm of break-down type an ejector for a cartridge case having a groove at its base, comprising an oblong, elastic arm, at the end of this arm a prong which engages the groove at the base of the cartridge case, a guiding groove in the body of the firearm, in guidance by which groove said arm moves axially when the firearm is broken performing ejection of the cartridge case, an ascending surface in the part of the bottom of said guiding groove adjacent to the base of the cartridge case, and a stop member on said arm opposite to said ascending surface in the range of the ejection travel so that at the rearward displacement of the arm when the firearm is broken, when said ascending surface and stop member meet the end of said arm is laterally deflected so that its prong moves outwardly from the groove of the cartridge case.
